Payment Gateway Integration

Payment Gateway Integration facilitates the acceptance of
electronic payment for online transactions.Payment Gateways are
software and servers that transmit Transaction information to
Acquiring Banks and responses from Issuing Banks (such as
whether a transaction is approved or declined). Essentially,
Payment Gateways facilitate communication within banks.

Security is an integral component of all payment gateways, as
sensitive data such as Credit Card Numbers need to be protected
from any fraudulent parties. The card associations have created
a set of rules and security standards which must be followed by
anyone with access to card information including gateways. This
set of rules and security standards is called the Payment Card
Industry Data Security Standard (PCI-DSS or PCI).

Submitting an order is usually completed using HTTPS protocol,
which securely communicates personal information through the
parties involved in the Transaction.

How does a payment gateway work?

Payment gateways work by providing the secure, integral link
between a website (web server) and the bank. When credit card
details are submitted on a website the payment gateway
receives these details and sends them to the bank for
verification. The bank then replies with a response; usually
either accepted or declined. The payment gateway then sends
this response back to the web server when the appropriate
message is displayed to the user - for example "Your payment
has been successful".

What is required for a payment gateway?

If you are looking at accepting real-time credit cards on your
website then a payment gateway is required. There are three
main requirements for a payment gateway to work:

1 . A website that meets the security and eligibility
requirements for the bank to issue a merchant account. 2 .
A merchant account from a bank. A merchant account is a
special kind of bank account that can be linked directly to a
payment gateway. These bank accounts are issued only upon
review of a website to ensure it meets privacy and security
requirements. Requirements often include an SSL certificate
and a privacy policy. 3 . A payment gateway provider.
Payment gateway providers offer the server that acts as the
link between your website and the bank. The server has a very
special configuration and a very high level of security due to
the sensitive nature of the data being transferred.

Once all three requirements are met, the payment gateway
then needs to be connected to the website and to the merchant
account. This will then allow for real-time credit card
processing.

What are the benefits?

By incorporating a payment gateway into your e-commerce
website you can ensure you are providing the easiest and most
streamlined buying experience for your customers. The easier
it is to buy from your online store the more likely visitors
are to purchase.
